ioat(4): Add support for interrupt coalescing

In I/OAT, this is done through the INTRDELAY register.  On supported
platforms, this register can coalesce interrupts in a set period to
avoid excessive interrupt load for small descriptor workflows.  The
period is configurable anywhere from 1 microsecond to 16.38
milliseconds, in microsecond granularity.
